Answer:
1.2
Step-by-step explanation:
The variance of a binomial distribution is:
σ² = n p (1 − p)
where n is the number of trials and p is the probability of success.
Given n = 5 and p = 0.40:
σ² = 5 (0.40) (1 − 0.40)
σ² = 1.2

Answer:
C
Step-by-step explanation:
Complementary means that the angles have a sum of 90° so we can write:
m∠A + m∠B = 90° → 3x + 2 + 8x = 90
11x + 2 = 90
11x = 88
x = 8 which means that m∠B = 8x = 8 * 8 = 64°.
Supplementary means that the angles have a sum of 180° so m∠C = 180° - m∠B = 180° - 64° = 116°.
